I agree that it seems like a stunt and her motives are questionable. However, the act seems unlikely to do harm, and at least has some potential to do good. Besides, I'd rather see this than watch her stick her tongue out again.

Admittedly, this is an awesome machine; however, this is a form a warfare that should have died when the cold war ended. When was the last time aerial battles had a major impact on the outcome of a war? An F-22 will provide little tactical advantage in places like Afghanistan. It's an extravagance and defense money could be better spent elsewhere.

I don't know how you can draw the conclusion that this isn't implemented because of a lack of profitability. It shows a mild preventative effect in a relatively small population of postmenopausal women. It is statistically significant, which only means it should be replicated. Even it is repeatable, it's certainly no cure for cancer. I doubt there is some vast conspiracy to keep this hushed...pharmaceutical companys and scientists are not out to kill us.

Common argument: I don't know for certain that Sasquatch, unicorns, and leprechauns don't exist, but I don't call myself agnostic on these matters. I'm an atheist when it comes to god for the same reason that I'm an atheist when it comes to Sasquatch. I accept the possibility that new evidence could prove me wrong.
